I just received an older production motor with the red "postage stamp" backplate.

Now, if I were to have any intention of mounting it somewhere useful I am going to need some advice from you guys who know so much!

Any advice, pictures, drawings or videos will be quite welcome.

There is a Goldberg plastic mount for that engine. I'll check. I may have a couple.

Say, ya got 4 holes there, you're only using two? Are they the diagonal two?

I think a postal worker would probably know best how to mount a postage stamp. I think you have to lick it first.

I always did like the later style as it had built in secondary mounting holes molded into them. Mine of course is this one. See picture.

Frank, I think you are on the right track but then if it were a Timex, instead of Cox, it could take a licking and keep on ticking! But then again I am not John Cameron Swayze, noted and respected newsman.

Jim, I think I remember the after market mount you refer to. Wasn't it molded of white nylon (or some such) and was packed with a piece of fuel line and a small balloon to be used as a fuel tank? Might have even had the mounting screws on the original packaging.

Yes, sir !!!

You are correctttoo- mundo, Johnny !!!

I use only two of the holes, on the bias. The holes are sized for #4 fasteners.

I just get back from test flying,, works fine.

That "postage stamp" looks quite a bit smaller than the current "product engine".

If had one, I'd probably fashion an oversize plywood plate for the back side. Hold it in place with the four crankcase bolts. Demel in some relief to make it fit snug.

Indeed the one I have is from an earlier time and is indeed smaller. Cox did make the product engine backplates more convenient to reuse by enlarging it some and placing four mounting holes. It resembles the Sure Start backplate only without the snorkel choke tube which was a later update.

Heh! I have no idea why I did not look right away but The cylinder in this one has dual ports! Better than a Golden Bee!

If the front end is healthy, just screw it onto the back end of an old engine.

Buy a new productin engine, you get a usable new backplate for $6.95. Plus some spare parts. And a new glow head.

Here's another shot of that backplate. It was created to fit in grooves moulded in the fuselage of an RTF. No other mounting facilities were considered. I intended to make an aluminum mounting plate for it but decided it was not worth it. As someone mentioned, just use the front end as a replacement for a worn out engine.

I think I will have to say that buying a new production motor (while they are still available) truly sounds like it holds the most merit.
So far I have yet to do so but now seems to be the time!

Thanks for all the replies guys!

I did think of one way. take two strips of quarter inch wide by one sixteenth aluminum, make them one and a quarter long and drill the crank case holes in them and new mounting holes on the outside ears and do it that way. While I think it would do in a pinch, once again the new production motor idea is the most sound.
